Question

(I+j) and (j+k)
What is the angle between two vectors​

Answer 1

Answer:

Let angle between ( i + j ) and ( j + k )

cos∅ = ( i + j ).( j + k )/|i + j| .| j + k |

|i + j | = √(1² + 1² ) = √2

|j + k | = √(1² + 1²) = √2

cos∅ = 1/√2.√2

= 1/2

cos∅ = cos60°

∅ = 60°

Answer 2

Answer:

What will be the angle between vectors (I+j) and (j+k)?. Angle between two vectors can be found from the formula: It means, the ...
